WebbPhenol can be distinguished from ethyl alcohol by all reagents excepta... Phenol reacts with NaOH, doesn't give Bromine water test but alchohol give Bromine water test and don't react with NaOH as pKa of alchohol is more than that of H2O but Na reacts with both phenol and alchohol so Na doesn't distinguish phenol and alchohol. hence D is correct WebbH2O mop HD, ångmopp. Hygieniskt rent hemma – desinficera helt utan kemikalier.
